May allow more room for exhaust (no angled upper bars).Can be installed beside frame-rail, inboard or outboard.
#PARALLELS PRO VS STANDARD INSTALL#
Slightly easier to visualize and install (bar mounts are built together).4 more attachment points to plot and install (parallel has bar mounts built together).

Angled upper bars can interfere with the fuel tank on late-model trucks.Angled upper bars can interfere with exhaust.Allows flexibility in bar placement to avoid obstacles.Less hardware to buy and install (no Panhard bar).NO side to side movement at all… you can run tighter tire to fender clearance.All else being equal, for the absolute rookie, the parallel may be a bit easier to visualize and understand during installation. You will spend more time with the tape measure than the saw or welder. With a parallel 4 link you are locked into a side frame link position… with a triangulated 4 link the lower links can be placed beside the frame or under the frame for clearance purposes.Įither system is very straight forward to install. A Panhard bar will also induce a small amount of side to side movement during suspension travel… not enough to feel but it mayĬoncern the customer who has an extremely tight tire to fender clearance. But a parallel 4 link requires a Panhard bar which adds slightly to the expense and can use up valuable space needed for your car or truck’s exhaust system. Universal parallel 4-links are therefore sometimes easier to install because the main link bars utilize a one-piece frame mount instead of two… less time in placing and welding the upper bar mounts. It connects the axle to the frame by way of links thereby allowing only up and down movement.Ī parallel 4-link fits most trucks better because the fuel tank is usually right in front of the axle, inboard of the frame. The Panhard bar runs perpendicular to the frame rails and horizontally across the vehicle.

A “Panhard bar” or other separate device is required to keep the axle centered. There is no need for a separate lateral locating device.Ĭonversely, with a parallel style 4-link, all bars are parallel to each other and the vehicle centerline. This is what keeps the rear axle centered under the vehicle. When connected securely to the axle and the frame, they form a “triangle”. On a triangulated 4-link the uppers bars are placed at an angle relative to the vehicle centerline. Like all Ridetech 4-links, this design features R-joint rod ends. Here is Ridetech’s universal triangulated 4-link rear suspension system. Beyond that one basic function, the two designs begin to differ. The upper 2 links keep the axle from rotating, keeping the pinion angle as constant as possible. The bottom 2 links keep the axle in place front to back. They locate the rear axle in the vehicle in its proper place. Triangulated 4-links and parallel 4-links accomplish the same thing. Although there are several theories as to which type of 4-link is “better”, it comes down to available space and preference.

A 4-Links is a great way to upgrade your car’s performance and ride quality - especially when compared to leaf springs. Let’s compare two popular types of 4-link rear suspension systems.
